Office electrical contractors | Occupied workplaces, fit-outs and tenant changes
Electrical Power for Offices & Commercial Buildings
Office electrical installations, additions and power upgrades across Scotland, including sockets, floor boxes, distribution, containment and dedicated supplies. WB Electrical plans the work around the people, systems and premises affected.
Based in Larkhall, we support offices and commercial buildings across Glasgow, Lanarkshire, Edinburgh and the Central Belt, with suitable project-led requirements elsewhere in Scotland considered by agreement.

Plan around people, premises and responsibilities.
Workplace changes drive electrical changes
When to involve an office electrical contractor
Office electrical work is often triggered by a change in layout, tenancy, occupancy or equipment rather than by a standalone electrical project. Early review helps resolve power, distribution, cable routes, access and specialist interfaces before furniture, IT and move dates become fixed.
The workplace or tenancy is changing
New desks, meeting rooms, reception areas, kitchens or collaboration spaces may need sockets, floor boxes, lighting changes and revised cable routes coordinated around the new layout.
Building services or technology need power
Comms rooms, UPS, HVAC, AV, access control, catering equipment and other defined loads may need dedicated supplies, isolation and clear responsibility between WB and the specialist supplier.
Existing infrastructure no longer suits the building
Distribution boards, sub-mains, containment, labels or available ways may need to change as occupancy and electrical demand develop.
Connected office installation requirements
Electrical installation services for offices and commercial buildings
A workplace change can affect more than one electrical element. WB can deliver a defined alteration or coordinate the relevant installation components around a refurbishment, tenant change or wider office project.
Additions and alterations
New circuits, relocated sockets, floor boxes, cleaner points, local supplies and electrical changes for desks, meeting rooms, kitchens, welfare areas and changing workplace layouts.
Use this route for defined changes to an existing installation where the job does not need a complete fit-out package.
Distribution boards and sub-distribution
Board replacements, alterations and new sub-distribution planned around existing office loads, retained services, available capacity and a practical changeover window.
Use this route when the main requirement is the board, sub-distribution or capacity-led distribution change.
Office fit-outs and refurbishment packages
Coordinated electrical packages bringing together distribution, containment, sockets, floor boxes, lighting, equipment supplies, testing and handover for new or refurbished workplaces.
Use this route where several electrical systems need to be delivered together against one layout, programme and handover.
When the workplace change needs supporting infrastructure
Containment & Conduit covers dado trunking, floor systems, tray, basket and conduit routes planned around finishes, access, cable separation and future changes. Specialist Power Supplies covers dedicated supplies for comms, UPS, HVAC, AV, access systems and other defined equipment loads.
For phased refurbishments, decants or defined short-term project needs, Temporary Power Solutions provides the route for temporary distribution where a suitable source and project arrangement can be established.
People, permissions and a workable programme
Plan office electrical work around the occupied building

Occupied offices bring together staff, visitors, critical systems, landlords, tenants and other contractors. Define the work area, responsibilities, access and acceptable interruption before the installation programme is fixed. Bring together available layouts, equipment data, landlord or tenant requirements, critical circuits, building rules and move dates. You do not need a finished electrical design before contacting WB, but the information already available helps identify what needs surveyed and coordinated.
01
Define the area and intended change
Confirm the building, floor or work area, occupancy, intended layout or equipment change, normal working hours, programme dates and the drawings or records already available.
02
Survey the electrical routes and interfaces
Review the relevant distribution, existing loads, cable routes, ceilings, raised floors, risers, access, isolation points and interfaces with IT, HVAC, fire, security, AV or furniture systems.
03
Agree access, isolations and responsibilities
Define the electrical scope, landlord and specialist interfaces, phasing or shutdown window, working-area controls, making-good boundary and the records required at handover.
Do not open electrical panels, lift floor tiles, enter ceiling voids or access restricted areas simply to gather quotation information. Existing documents, safely visible labels and ordinary site photographs are enough to begin the review.
Have a layout, equipment schedule or move date? Send the office electrical requirement to WB.
From installation to a usable workplace record
Testing and handover for the work completed
Office handover should make clear what was installed or altered, what was inspected and tested, how the relevant circuits and equipment supplies are identified, and what remains outside the agreed electrical package.
For each completed package
- Inspection and testing appropriate to the electrical work completed.
- Applicable electrical certificates, test records and circuit or equipment identification.
- Updated schedules, marked-up information or product details where these form part of the agreed handover.
- Separate defects, retained systems and follow-on recommendations identified rather than silently added to the completed scope.
Across tenants, floors or several premises
Use consistent building, floor, room and project references so quotations, isolations, handover records and follow-on work can be matched to the correct location. Landlord, facilities and specialist-system requirements should remain visible throughout.
A defined electrical installation package does not automatically create a wider EICR, structured-cabling certificate, fire or security record, HVAC commissioning report or landlord completion pack unless those outputs are expressly included.
Where the office project needs wider contractor coordination: WB can support the electrical interfaces within a broader building-services package while keeping each specialist contractor’s responsibilities clear. Explore M&E Project Support.

Electrical support across Scottish Opera’s Glasgow estate

Scottish Opera
WB Electrical has supported Scottish Opera since 2015 across four Glasgow locations covering rehearsal, production, workshop, storage, welfare, office and external spaces.
The published work includes new distribution panels, rewiring, sockets, ventilation supplies, lighting and emergency lighting, inspection, testing and remedial activity, coordinated with the onsite maintenance team across occupied and operational premises.
Supplier assurance
For contractor selection and procurement, review WB’s current accreditations and certificates. Tell us about landlord, supplier-onboarding, insurance or project-document requirements when enquiring.
Before the scope and programme are agreed
Office and commercial power questions
Can electrical work be planned around an occupied office?
Often. Depending on the work, the programme may use phased areas, preparation before isolation, agreed evening or weekend access, exclusion zones and advance notices. The method depends on the affected circuits, occupancy, building rules and safe access, so zero disruption should not be assumed before survey.
Can WB add sockets and floor boxes for desk moves or hot-desking?
Yes, where the existing installation, route and capacity are suitable. Desk and furniture layouts, floor construction, data routes, cleaner points and future flexibility should be reviewed together before final positions are fixed.
Can distribution boards be upgraded in a live commercial building?
Potentially. The existing board, loads, retained services, records, changeover route and acceptable interruption need to be reviewed first. Pre-installation, phased work or a planned isolation may be used where the final design and site conditions allow.
Can power, lighting and data work be coordinated within one office project?
Yes. WB can coordinate the defined electrical installation with lighting, containment and data requirements, or work alongside appointed specialists. The project should record who supplies, installs, connects, tests and commissions each system.
Who is responsible for landlord approvals and tenant alterations?
That depends on the lease, building rules and project appointments. The client should confirm landlord, tenant and freeholder permissions and completion requirements. WB can then define its electrical scope around those responsibilities.
Need lighting or workplace cabling as well? See Office & Commercial LED Lighting. For structured cabling and network infrastructure, explore Data & Connectivity Infrastructure.
One office, a managed building or a multi-site portfolio
Request an office electrical review or quotation
Tell us what is changing, how the workplace is used and the programme you are working towards. WB can advise whether the next step should be a records review, site survey, defined quotation or wider project discussion.
Useful information to send
- Building, floor and affected work-area location, plus normal occupancy and working hours.
- The required change, such as desks, sockets, floor boxes, equipment, distribution, fit-out or refurbishment.
- Available furniture layouts, drawings, load data, board information, equipment data sheets or photographs.
- Landlord or tenant responsibilities, critical services, access rules and acceptable interruption windows.
- Move date, project programme and the IT, furniture, HVAC, fire, security or AV parties involved.
Missing drawings or confirmed quantities need not stop an enquiry. Send the information you already have and identify any landlord, IT or building-management contacts who may hold the remaining records.
What affects an office electrical quotation?
Scope, quantities, existing distribution and capacity, cable routes, ceilings or raised floors, working hours, access, phasing, specialist interfaces, equipment data, testing and handover requirements all affect price. Some work can be quoted from clear information; other projects need a survey first.
The quotation defines the electrical work WB is taking responsibility for. IT configuration, fire and security design, HVAC controls, AV programming, furniture systems, landlord approvals and specialist commissioning remain with the relevant party unless expressly included.
